This is my Emacs configuration, which is certainly in it’s early days. The
init.el file tangles this file using org and loads it as configuration. I use
this repository by cloning it to my home folder. Generally, I’ll have already
installed nvm. Until I can figure out a better way, after cloning this, you
should go into the /tern folder and run npm install to install tern’s
dependencies.
